An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.

On Windows XP Service Pack 1, Windows XP Service Pack2, Windows Server 2003 and Windows Server 2003 Service Pack1 SafeDllSearchMode is set to 1 by default and is not affected. If this default configuration is modified by an Administrator or is disabled those systems could be susceptible to the vulnerability.

Microsoft has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.

Set SafeDllSearchMode to 1 Setting SafeDllSearchMode to 1 within the registry ensures the DLL search path order targets the system directory before the current working directory or User Profile directory. For more information about Dynamic Link Library search order please read the following MSDN article.
Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.
Note We recommend backing up the registry before you edit it.

What is the scope of the vulnerability?This is a privilege elevation vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To attempt to exploit the vulnerability, an attacker must be able to log on locally to the system and run a program.

What causes the vulnerability?On Windows 2000 Winlogon does not prohibit the use of an invalid path. If a specially crafted DLL is placed in the user directory, it is possible for WinLogon to execute the code of the DLL resulting in an elevation of the user’s privileges.

What is Winlogon?Winlogon is the process that manages security-related user interactions in Windows. It handles logon and logoff requests, locking or unlocking the machine, changing the password, and other requests.

What is a DLL?A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined. Although a DLL can export data, its data is generally used only by its functions. However, there is nothing to prevent another module from reading or writing that address. DLLs provide a way to modularize applications so that their functionality can be updated and reused more easily. DLLs also help reduce memory overhead when several applications use the same functionality at the same time, because although each application receives its own copy of the DLL data, the applications share the DLL code. For more information on DLLs please ready the following MSDN article.

Is my Windows XP and Windows 2003 vulnerable since I do not see the SafeDllSearchMode registry key?No. On Windows XP Service Pack 1, Windows XP Service Pack 2, Windows Server 2003 and Windows Server 2003 Service Pack1 SafeDllSearchMode is set to 1 by default within the operating system code and is therefore not vulnerable. Adding the registry key with a value other than 1 will change the default configuration. For more information about SafeDllSearchMode configuration options please read following MSDN article.

What might an attacker use the vulnerability to do?An attacker who successfully exploited this vulnerability could take complete control of the affected system.

Who could exploit the vulnerability?To try to exploit the vulnerability, an attacker must be able to log on locally to a system and run a program

How could an attacker exploit the vulnerability?To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then place a specially crafted DLL within their UserProfile directory and then restart the computer. After the restart and subsequent re-logon by the attacker, the DLL would execute code that could exploit the vulnerability and allow the attacker to gain complete control over the affected system.

What systems are primarily at risk from the vulnerability?Windows 2000 systems are primarily at risk. Servers could be at more risk if users who do not have sufficient administrative permissions are given the ability to log on to servers and to run programs. However, best practices strongly discourage allowing this.

Could the vulnerability be exploited over the Internet?No. An attacker must be able to log on to the specific system that is targeted for attack. An attacker cannot load and run a program remotely by using this vulnerability

What does the update do?The update removes the vulnerability by not allowing WinLogon to use an invalid path on Windows 2000.

When this security bulletin was issued, had this vulnerability been publicly disclosed?No. Microsoft received information about this vulnerability through responsible disclosure

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

Unhandled Exception Vulnerability - CVE-2006-3648:

There is a remote code execution vulnerability in the way that exception handling is managed on multiple applications that are resident in memory.

An attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.

An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights

The Restricted sites zone helps reduce attacks that could try to exploit this vulnerability by preventing Active Scripting and ActiveX controls from being used when reading HTML e-mail. However, if a user clicks on a link within an e-mail they could still be vulnerable to this issue through the Web-based attack scenario described previously

Workarounds for Unhandled Exception Vulnerability - CVE-2006-3648:

Microsoft has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.

Disable active scripting in the My Computer zoneMore information on the values being modified by this workaround can be found at the following Web site. There are two ways to deploy this workaround:
Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.
Note We recommend backing up the registry before you edit

In Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0

Double click the DWORD Value: 1400.

The Edit DWORD value dialogue appears. The default value is 0. Change this value to value to 3.

Close any instances of Internet Explorer. The change takes effect the next time Internet Explorer is started.

Read e-mail messages in plain text format if you are using Outlook 2002 or a later version, or Outlook Express 6 SP1 or a later version, to help protect yourself from the HTML e-mail attack vector.Microsoft Outlook 2002 users who have applied Office XP Service Pack 1 or a later version and Microsoft Outlook Express 6 users who have applied Internet Explorer 6 Service Pack 1 or a later version can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.

Digitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.

Impact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:

The changes are applied to the preview pane and to open messages.

Pictures become attachments so that they are not lost.

Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.

Verifying that the Update Has Been Applied

Microsoft Baseline Security AnalyzerTo verify that a security update has been applied to an affected system, you can use the Microsoft Baseline Security Analyzer (MBSA) tool. MBSA allows administrators to scan local and remote systems for missing security updates and for common security misconfigurations. For more information about MBSA, visit the Microsoft Baseline Security Analyzer Web site.

File Version VerificationNote Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

Click Start, and then click Search.

In the Search Results pane, click All files and folders under Search Companion.

In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.

In the list of files, right-click a file name from the appropriate file information table, and then click Properties.

Note Depending on the version of the operating system or programs installed, some of the files that are listed in the file information table may not be installed.

On the Version tab, determine the version of the file that is installed on your computer by comparing it to the version that is documented in the appropriate file information table.

Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.

Registry Key VerificationYou may also be able to verify the files that this security update has installed by reviewing the following registry key:

Note This registry key may not contain a complete list of installed files. Also, this registry key may not be created correctly when an administrator or an OEM integrates or slipstreams the security update into the Windows installation source files.

Microsoft thanks the following for working with us to help protect customers:

Customers in the U.S. and Canada can receive technical support from Microsoft Product Support Services at 1-866-PCSAFETY. There is no charge for support calls that are associated with security updates.

International customers can receive support from their local Microsoft subsidiaries. There is no charge for support that is associated with security updates. For more information about how to contact Microsoft for support issues, visit the International Support Web site.

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop systems that are running Windows 2000 Professional or Windows XP Professional.

Microsoft Systems Management Server (SMS) delivers a highly configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and can perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer, the Microsoft Office Detection Tool, and the Enterprise Update Scan Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, visit the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
